Mercedes Fuel Drain

ABOUT

Putting Petrol in a Diesel Mercedes is a usual mistake. And its remedy is dependent upon several different things. In the event that you would like to know what you must do to sort it out then please read on.
Listed here the key factors to to consider when choosing whether to have a fuel drain:

  1. How much Petrol did you put in the Mercedes, taking into account that the fuel tank capacity of your Mercedes C350 CDI is probably approximately 66 litres?
    1. A tiny amount of Petrol, less than 3.3 litres of Petrol in a Diesel C350 CDI will more often than not not be a major problem. Experience has demonstrated to us that anything under 3.3 litres (close to 5% of the entire fuel tank capacity) is generally able to be adequately diluted through completely topping up the remainder of the tank with Diesel.
      It is pretty unusual to encounter a motor vehicle having problems due to below 5% wrong fuel contamination. Remember that it is very infrequently found - certainly not impossible to encounter. You can get certain automobiles that won't endure any degree of contamination in the slightest.
    2. Anywhere between 3.3 and 6.6 litres of Petrol in the Mercedes (5 to 10%) is a 50/50 situation. Our experience has proven that as many motorists get away with it as those who break down. Any time you are figuring out whether or not to chance it and just simply fill it up recognise that it is the same as wagering it all on black - you will have a 50/50 chance of it being ok.
    3. Anything over 6.6 litres of Petrol in your Diesel C350 CDI should really straight away be drained seeing that your probability of getting away with that amount of contamination is more than likely less than one in fifty - really long odds.
  2. Put some Petrol in a Diesel Mercedes and drove it: Have you spotted any kind of performance problems ever since putting the incorrect fuel in your C350 CDI? In that case, have it removed no matter the quantity of Petrol or the contamination percentage. Proceeding to run running an automobile that is currently beginning to suffer from the effect of fuel contamination will probably likely end up in increasing amounts of harm being caused to the fuel system parts.
  3. Are you looking for peace of mind?
    You should get it drained. Whatever the contamination ratio, there is invariably some extent of threat resulting from driving a Diesel motor on Diesel contaminated with Petrol. Possible final outcomes of driving on the wrong fuel include things like the motor not starting, running unevenly, losing power, wearing of the high-pressure pump, worn or bunged injectors, and so forth. These are some of the most typical Petrol in Diesel warning signs, and in the event that you detect any of them then stop driving and get it drained as soon as possible.

Petrol in Diesel Questions

When someone has put Petrol in a Diesel car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Petrol in a Diesel car and drove it. What do I do?

Answer

Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Diesel car on Petrol cause damage to it?

Answer

It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Petrol can I get away with in a Diesel car?

Answer

The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?

Answer

Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?

Answer

No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Diesel and add some 2-stroke oil?

Answer

This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
